------------------------------------

             Summary: LeaderSelector has no response when delete the leader node by other clients
                 Key: CURATOR-49
                 URL: https://issues.apache.org/jira/browse/CURATOR-49
             Project: Apache Curator
          Issue Type: Bug
          Components: Recipes
    Affects Versions: 2.1.0-incubating
         Environment: curator-recipes 2.1.0-incubating and  zookeeper 3.4.5
            Reporter: Ding Jinqiang


If I setup a normal LeaderSelection with two participants, and as expected one of them becomes the leader. But when I delete the leader node manually by other clients, the other leaderSelector becomes the leader normally. But the leaderSelector, which is the previous leader, does not receive any notification in the LeaderSelectorListener. 

Well, my question is, is this normal, or I just missed something? 

Sample code may like this:

		RetryPolicy retryPolicy = new ExponentialBackoffRetry(1000, 1);
		client = CuratorFrameworkFactory.newClient(Config.getInstance().getServerConnectString(),
				retryPolicy);
		client.start();
 		LeaderSelectorListener listener = new LeaderSelectorListener() {

			@Override
			public void takeLeadership(CuratorFramework client) throws Exception {
				logger.info("takeLeadership, thread id:"+Thread.currentThread().getId());
 				Thread.sleep(Long.MAX_VALUE);
			}

			@Override
			public void stateChanged(CuratorFramework client, ConnectionState newState) {
				logger.info("Zookeeper connection stateChanged, new state is " + newState);
			}
		};
		selector = new LeaderSelector(client, Config.getInstance().getEclectPath());
		selector.autoRequeue();
		selector.start();
